Problems solved by technology

[0002] At present, in the bulb-shaped high-power fluorescent lamps and light-emitting diode lamps of the prior art, about 80% of the input power will be converted into heat energy, and the main heat comes from the lamp tube and the light-emitting diode tube core, the lamp tube and the tube of the bulb-shaped lamp. The core is sealed in the bulb, and the heat is difficult to dissipate effectively, thus causing the temperature of the lamp tube and the tube core to be too high, which seriously reduces the luminous efficiency and life of the lamp, that is, it is difficult to make a high-power bulb-shaped, high-efficiency, long life lamp

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with accompanying drawing: figure 1 Shown is a schematic diagram of the principle of the superconducting heat pipe lamp of the present invention. figure 1 It includes a light-emitting device 1, a light-transmitting bulb 4, a driver and its casing, and an electrical connection device. The light emitting device 1 can be at least one hot cathode or cold cathode fluorescent tube, at least one light emitting diode tube core or other light sources; at least one superconducting heat pipe 2, wherein 2a is its heat-absorbing end, where the light-emitting device 1 absorbs heat On or near the end 2a, the cooling end 2b of the superconducting heat pipe is connected to a cooling device 3, which includes cooling fins 3a, and the heat released by the superconducting heat pipe 2 can be effectively dissipated through the cooling device 3. Since the superconducting heat pipe 2 has an ultra-high thermal conductivity t...

Abstract

The present invention relates to a heat superconducting tube lamp, including a luminou device, for example, at least a hot-cathode or cold-cathode fluorescent light tube or at least a light-emitting diode, a light transmission bulb shell, a driver and its shell and an electric connector, also including at least one heat superconducitng tube, the luminous device is positioned on the surface of heat-absorbing end of the heat superconducting tube or near by it and a heat abstrator which is tightly and thermally contacted with heat-releasing end of heat superconducting tube, and the described heat superconducting tube can effectively pump out the heat quantity from luminous device and make the heat quantity pass through the heat abatractor to diserse so as to make luminous device work at low temp. It can be made into high-power high-efficiency and long-life lamp.

Description

technical field [0001] The invention relates to a bulb-shaped high-power, high-efficiency, long-life hot-cathode or cold-cathode fluorescent lamp and light-emitting diode lamp, which can directly replace tungsten filament lamps and compact fluorescent lamps, and can be used for lighting, traffic lights and displays. Background technique [0002] At present, in the bulb-shaped high-power fluorescent lamps and light-emitting diode lamps of the prior art, about 80% of the input power will be converted into heat energy, and the main heat comes from the lamp tube and the light-emitting diode tube core, the lamp tube and the tube of the bulb-shaped lamp. The core is sealed in the bulb, and the heat is difficult to dissipate effectively, thus causing the temperature of the lamp tube and the tube core to be too high, which seriously reduces the luminous efficiency and life of the lamp, that is, it is difficult to make a high-power bulb-shaped, high-efficiency, Long life lamp.
